Application filed January 12,-1927. -Serial fNp.160,574.u

My invention relates to'a new improved vtrap 'l'or refrigerators or the like in which the liquid is allowed to pass through the trap but the passage ot `air in either direction is eti'ectively blocked, for Va refrigerator is effective only when coldfair is kept in and when air or gases are kept out,'and the objects of my invention are to make a trap that will serve these' purposes .more effectively andone which `will begin to v,operate when the liquid reaches the desired level lin its container, and one which will not'draw` out too much liquid, also my trap canrbe. easily cleaned -out and it will not `easily get -lout .of order. W ith these and other objects in view, the invention consists in certain :novel parts and ar-ran gements of part-sas will inore fully appear -as the description proceeds, the novel Vtentures .thereof being pointed out in theI appended claims.

'F a tull understandinu ot the invention, reference is to be had to the following description andthe accompanying drawings, in whichi Figure l is ia vertical sectional view oi. the trap in the liquid receptacle in the bottom ot a refrigerator.

rij refrigerator Alhas a liquid receptacle l which receives water from the ice compartment, sli-own, through pipe 2. `Pipe 2 is shown passing through food chamber 3 of the refrigerator. A

3e 5 passes out of the bottom of the re rigerator and may be connected with a ewer or other drain means. This pipe asses upwardly through the bottom of the liquid receptacle, with a tight joint, with said bottoni. Soldered at its upper corners into this pipe is a long square cup 6. At the desiredlevel of the liquid pipes branch from a common center downwardly to near the bottoni` of the receptacle, as pipes 8 and 9. At the common center these pipes are connected to a pipe l7 passing down into said cup to near its bottom. Another pipe 10 is soldered to the outside of the center of pipes 8 and 9, enclosing the upper part of pipe 7,

'pipes were made.

3. In a trap for a refrigerator or the like, a liquid receptacle, a pipe extending `up` wardly through the bottoni of said recepf ktacle, a cup in said pipe, a space between the walls of said cup and pipe for the passage of liquid therethrough, two opposite radially directed pipes extending from near the desired surface of liquid in said receptacle to near the bottom of said receptacle, said radially directed pipes, at their center of radiation, being connected together and to a pipe extending down into said cup, said last named pipe and cup having a space between their respective walls for the passage of liquid therethrough, and means to support said radially directed pipes and to seal the space between them and the pipe extend ing into said cup and said first named pipe whereby the level of liquid in said receptacle is maintained substantially at the point of overflow of said two opposite radially directed pipes.

4. In a trap for a refrigerator or the'like, a liquid receptacle, a pipe extending upwardly through the bottom of said receptacle, a cup in said pipe, a space between the walls of said cup and pipe for the passage of liquid therethrough, a plurality of radially directed pipes extending from'rnear the desired surface of liquid in said receptacle to near the bottom of said receptacle, said radially directed pipes, at their center of radiation, being connected together and to a pipe extending down below the lower ends of said'radially directed pipes and into said cup, the pipe extending into `the cup and the cup and pipe havinga spacebetween their respective wallsV for the passage of liq- `uid therethrough, and means t support said radially directedV pipes and to seal the space between them and the pipe extending into said cup and said first named pipe whereby the level of liquid in said receptacle isniaintained substantially at the point of overow of said plurality of radially directed pipes.

5. In a trap for a refrigerator or the like, a liquid receptacle, a pipe extending upwardly through the bottom of said receptacle, a cup in said pipe, a space `between the walls of said cup and pipe for the passage of liquid therethrough, a plurality of radially directed pipes extending from near the desired surface of liquid in said receptacle to near the bottom of said receptacle,

said radially directed pipes, at their center of radiation, being connected together and to a pipe extending down intosaid cup, said last named pipe and cup having a space between their respective walls for the passage of liquid therethrough, the top of said cup being above the lower ends of said radially directed pipes and means to support said last namedpipes and to seal the space between them and the pipe extending into said cup of. liquid therethrough, a plurality of radially directed pipes extending from near the desired surface of liquid in said receptacle to near the bottom of said receptacle, said radially directedpipes, at their center of radiation, being connected together and to a pipe extending down into said cup, said last named pipe and cup having a space between their respective walls for the passage of liquid therethrough, and a pipe having a liquid tight connection with said first named pipe at one end, and with said radi* ally directed pipes and the pipe extending into said cup at the other end whereby the level of liquid in said receptacle is maintained substantially at the point of overflow ofsaid plurality of radially directed pipes.
